Hello, is there a way to disable trace reflection / refraction in vray hair3 mtl? hoping more speed increase in rendering.
im using maya 2018 & vray 3.60.04
I don’t think there is a way to do that, but you could try lowering down the Transmission and the Primary Amounts and see you if that would help.
What do you need the speed increase for: look-development or final renders?
For the former, you can raise Noise Threshold in the render panel, and that will lower the amount of work V-Ray will have to accomplish.
As for finals, the shading model relies entirely on tracing, even to establish color, so there is no way to turn those off.
A simpler shading model, which is also quicker, is the old hair shader.
But looks will be quite different, be warned.
Hello, thanks for the input Nikolai Kusht & lele, its for final result & production, will try to reduce transmission. Thanks
